During my keynote at GUADEC this year I
mentioned that we should not just look for people who can contribute on
the same level as we do in the Free Software community. But that we need
to find actions, with a low barrier to participate so our friends,
parents, children can also take part.

This includes showing others that you support software freedom by using
T-shirts, bags, pins, or stickers. I was mentioning that once in Berlin
I saw a GNOME sticker over the button of a pelican crossing. But
unfortunately I could not find that picture before the talk as I
remembered it just the night before the talk, and could not find it on
my laptop. Still, during GUADEC several people asked me about that
picture again. All I could say was that it was during one of the
Linuxtage in Berlin. On my way back I checked my laptops's hard disk
again, but still without success.

A few weeks ago while I was polishing up the notes for the speech about
universal
computing---so
others can reuse them when talking about software freedom---I remembered
the picture and I challenged myself to find it. So I spent some more
time to dig through my backup disks. Finally I found it, and this week I
was also able to find out who the author is.
